Field of the Invention
The present invention is related to a heat dissipating fan, in particular, to a slim-type fan structure.
Description of Related Art
As the technology of the computer industry advances, fans have become one of the essential components for heat dissipation in the computer nowadays. These fans are able to not only satisfy the needs for heat dissipation but also configured to cope with the lighter and slimmer designs of computers or 3C products in order to overcome the limitations on the available space and the dimensional requirements as well as the considerations on the reduction of the weight for lighter products.
However, currently, a typical heat dissipating fan must include a stator and a rotator; wherein the rotator refers to the fan blade of the fan, and for a conventional fan blade, it includes at least one blade wheel and a plurality of blades arranged at the outer perimeter of the blade wheel. In addition, a magnetic unit is disposed inside the blade wheel in order to perform an electromagnetic induction with the stator. Furthermore, the center of the blade wheel further includes an axial center or an axial sleeve provided for a pivotal arrangement thereon. Therefore, obviously, such known fan blade is not simplified in its structure nor configured to be slim in the structure; as a result, it is an assembly structure that requires each component part to be assembled with each other. Moreover, since each component part needs to be made of a heavier material, the overall structure is not slim in its dimension nor is light in weight, which may even require more assembly procedures and may involve greater costs during the manufacturing thereof. Therefore, there is a need for an improvement.
In view of the above, the inventor seeks to overcome the aforementioned drawbacks of the currently existing technique and provides an improvement after years of research and development along with the use of academic principles in light of solving the aforementioned problems.
An objective of the present invention is to provide a slim-type fan structure, which is able to utilize a stator of the fan being made from a circuit board and a plurality of layout circuits disposed thereon in order to achieve the slim design of the fan.
Another objective of the present invention is to provide a slim-type fan structure, which is able to further allow the fan blade of the fan to be integrally formed of a magnetic material in order to achieve the slim design of the fan.
To achieve the aforementioned objective, the present invention provides a slim-type fan structure comprising: a stator, a fan blade and a fan shield. The stator further comprises a circuit board and a plurality of layout circuits disposed to circumference the circuit board, and the stator includes an axial center at a center portion thereof. The fan blade comprises a blade wheel, an axial sleeve arranged at a center of the blade wheel and extended axially therefrom, a plurality of blades formed to circumference an outer of the blade wheel, and a magnetic unit disposed on the blade wheel. In addition, the axial sleeve is configured to pivotally attach to the axial center. The fan shield covers an outer of the fan blade, and the fan shield includes a fixation portion provided to secure the axial center. According to the above, the magnetic unit is formed by a plurality of N pole areas and a plurality of S pole areas arranged alternatively in circular rows and arranged corresponding to the plurality of layout circuits along a vertical direction in order to achieve the slim-type fan structure.
To achieve the aforementioned another objective, the present invention provides a slim-type fan structure; wherein the magnetic unit of the fan blade is manufactured by mixing a magnetic material with a material of the fan blade in order to integrally form the fan blade.
The following provides a detailed description of the present invention along with the accompanied drawings; however, it shall be understood that the accompanied drawings are provided for illustrative purposes only, which shall not be treated as limitations of the present invention.

Furthermore, as shown in
According to the above, with the aforementioned structural assembly, a slim-type fan structure of the present invention can be achieved.
As a result, based on the slim-type fan structure disclosed by the present invention, the stator 1 can be mainly constructed from the circuit board 11 and the plurality of layout circuits 12 in order to achieve the slim design of the fan structure. In addition, the fan blade 2 is further integrally formed with a magnetic material mixed therein such that the design of the present invention has the merit of being light in weight. Therefore, the overall performance of the fan can be enhanced and the quality of the product can be increased.
